Precautions for Correct Use
• Backing up data to the Memory Cassette can be performed only when the
G9SP-series Controller's configuration data is locked. Conduct a safety
confirmation test (i.e., user test) and lock the configuration data before
performing the backup.
• Complete backup in advance, before using the G9SP-series Controller if
the Memory Cassette is going to be used for efficient replacement of the
G9SP-series Controller in the event of failure. Backup may not be per-
formed correctly after failure of the G9SP-series Controller.
• Performing a backup overwrites the data on the Memory Cassette. Be
sure to confirm that the Memory Cassette contains no required data
before performing backup.
Note (1) Formatting the Memory Cassette is not required.
(2) The contents of the Memory Cassette can be checked by verifying the
configuration ID to prevent setting incorrect configuration data when re-
storing data to the G9SP-series Controller is performed from the Memory
Cassette. To enable performing this verification, record the configuration
ID when performing backup.
